Written Answer by Deputy Prime Minister and Minister for Trade and Industry Gan Kim Yong

1. Currently, 6% of private residential properties have solar panel installations on their rooftops. The number and capacity of grid-connected solar installations on such properties have risen steadily over the past five years (see Table 1).

2. The number and capacity of grid-connected solar installations deployed by private sector entities across public and private non-residential properties have also risen steadily over the past five years (see Table 2). Due to our current data collection methodology, we do not have data on the proportion of private non-residential properties that have solar installations.

Note: Figures are from SP Power Grid Ltd and EMA, and are based on solar installations as the end of each calendar year.
